The Brave browser for the desktop links the functionality of the Wayback Machine to a 404 error message. If a searched page is not found and a 404 message follows, users can have the page automatically search the Wayback Machine archive.
The Internet Archive, the organization behind the Wayback Machine, reports that this feature is available in the new desktop version 1.4 from Brave. This automated Wayback Machine search process was previously available via extensions, but is now a standard part of the latest desktop version.
Users with this version of Brave get a 404 error message, the message that the page is unfortunately not found, the question if they want to see if a saved version of the page is available on the Wayback Machine. By clicking on the button displayed, this search process is started. The function works in total with fourteen different http error codes and therefore not only with a 404 message that the page was not found. These are, for example, codes 408, 410, 451, 500, 502, 503, 504, 509, 520, 521, 523, 524, 525 and 526.
The Internet Archive says it has archived over 900 billion URLs and over 400 billion web pages with the Wayback Machine for 23 years, adding hundreds of millions of URLs every day. “As a result, there is a good chance that an archived version of the page that has not been found is available,” said the Internet Archive.
